needs some Thoughts on Shift Points with my power band
We are going to the track this week. wanted to get some of your guys thoughts on my shift points with my power band
I can rev this motor to 11,000rpms no problem so i can keep her in spool
I have a 05 5 speed with a evo 9 first gear if that helps

Also have a hand brake which will let me wind her up out of the hole

have you ever calculated thrust curves?
you basically multiply out your torque by each gear, all on the same graph. that way you can see where the applied torque crosses from gear to gear. you generally want to stay in the lowest gear possible depending on how drastically it falls off.
in general people get tripped up, by the fact that power is plateauing, but never account for the fact that gearing almost always makes a bigger difference than the power curve. so unless you have some crazy torque dropoff (which you don't) you want to wind out each gear
edit: the X axis is usually MPH.
